dang dee seems the rep rugers have for bad groups may not be deserved. funny my ruger shot the 140 grain hornady ammo all over the place to, in factory ammo mine luved 130 grain rem cor loc better than anything. as said I have a load with a SIERRA gameking 130 boatail that I can shoot 1 and 1/4 to 1 and 1/2 group with now, hope to get them down to at least sub MOA, CHAD I will bed and float new stock and see what happens group wise,i to questioned the effect neck sizeing would have. my mentor in reloading is a pro neck sizeing fellow. I reloaded my first round in 2013 so an fairly new at it, am learning some things are ford chevy and blond vs dark haired things. chad do you recommend bedding myself or getting a smith, am fairly handy with tools am a machineist and millwright, and would luv to learn the art, thanks guys and good hunting and shooting.
I'd say give bedding a try yourself. You can watch many youtube videos on how to do it and prep the stock and action. The bedding compounds even come with instructions. I know many shooters that learned how to do it by bedding their own rifles. I would not feel comfortable or relying on a decent mating of the new stock to your action by just dropping it in without bedding it. There WILL be gaps and pressure points. Where those gaps and pressure points are, could easily cause some consistency issues. If the goal is top accuracy out of a factory rifle, bedding it is the way to go.
Neck sizing is up to you. You WILL have to keep a closer eye on your brass and do some chamber checking once you have your ammo loaded. I have been down the road on neck sizing, and it's not worth it to me. But I do know a lot of shooters that do this. You just have to make sure you can still chamber a loaded round after neck sizing. There will be some that chamber tight or won't chamber at all. These rounds that chamber tight or won't chamber will have to be taken apart and reloaded. So, I'd rather have 100% reliable chambering each time, and go the FL bump or FL sizing.
